WlCK-RAISER FOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 414,948, dated November 12, 1889.

Application filed May 13, 1889.

To all whom it may concern.-

Be itknown that I, JOHN C. MILLER, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in VVick-Raisers for Central- Draft Lamps; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a vertical central section of a fount, showing side view of the wick-adj usting mechanism with the rod engaged'with the wick-holder; Fig. 2, the same parts with the rod raised and with the finger withdrawn for the introduction or removal of the wickholder, as the case may be; Fig. 3, a transverse section on line 00 m of Fig. 1; Fig. 4, a perspective view of the wick-raising rod detached.

This invention relates to an improvement in wick-raisers for that class of lamps in which the Wick is of tubular shape and arranged around the central tube in the fount, through which tube air is admitted to the top of the wick to support combustion, commonly called central-draft lamps,and particularly to that class in which the wick-adjuster consists of a vertical rod arranged to slide up and down through the top of the fount outside the burner and engage with the wick within the fount, so that raising or lowering the rod will correspondingly adjust the wick, the object of the invention being a simple construction of this class of wickraisers, whereby the wick-holder with the wick may be easily removed or introduced, 40 as the case may be, without the removal ofthe lifting-rod from the fount, and it consists in the construction as hereinafter described, and particularly recited in the claims.

A represents the fount of a lamp of common construction; B, the wick arranged around a central tube C, and so as to be adjustable thereon. The wick is carried bya sleeve D, arranged upon the central tube C and within the wick, and so that by the adjustment of this sleeve up and down the wick will be Serial No. 310,548. (No model.)

correspondingly raised or lowered. The sleeve D is removable from the central tube for the application of the wick. The wick is placed over the sleeve D, and there secured in any convenient manner, preferably by a metal band E, surrounding the wick, and so as to clamp the wick so firmly upon the sleeve as to insure such engagement between the wick and sleeve that the wick will positively move with the sleeve.

. On one side of the sleeve D is a radial vertical rib F. The band E passes through an Opening Gin this rib, the band being a divided metal ring, as represented in Fig. 3, its two ends a, b constructed to be united, pref erably, by a hook and eye, as represented in Figs. 1 and 3, but so as to bind the wick upon the sleeve, as before described.

H represents the rod, which is arranged through a suitable guide I in the top of the fount and so as to support the rod in its vertical position, yet permit it to be moved freely up or down. The lower end of the rod is turned upward to formaspring-finger J. (See Fig. 4..) The rod and spring are best made from round wire, the lower end flattened to form the spring J, as shown. Through this spring-finger J a vertical slot K is formed, which in size corresponds substantially to the vertical rib F on the sleeve, and so that in operation the rib F projects through the slot K in the spring-finger J, and so that the raising of the rod will cause a corresponding up or down movement of the sleeve D and the wick it carries. 7 S 5 The upper end of the fingerJ is curved outward or toward the rod H, as shown, and extends some distance above the rib, and so that when the rod is raised the spring-finger will pass through the neck of the fount, as repre- 9c sented in Fig. 2, within reach of the person trimming the lamp, and so that the person may draw the fingerJ outward and away from the rib F, as represented in Fig. 2, thus detaching the lifting-rod from the sleeve, so that 9 5 the sleeve with the wick may be removed from the fount, as for renewing the wick or other purpose for which it may be desirable to remove the sleeve, and when the sleeve is again returned onto. the central tubeitpasses I00 down, strikes the outwardly-turned end of the springfiuger J, the spring yields, so that the rib will pass down until it comes into line with the groove K in the spring-finger, and then the reaction of the spring will force the finger onto the rib, as seen in Fig. 1, to make suitable engagement with the wick.

Preferably the upper end of the slot K is made flaring or somewhat broader than the thickness of the rib to faeilitatethe introduction of the rib to the spring; but this is not essential to the invention.

By this construction of wick-adjusting device the rod retains its engagement with the wick-carrier and without liability of accidental detachment, yet permits easy detachment from the wick when occasion requires.

1 have represented the wick-holder a sleeve sliding upon the tube with thepvick outside the sleeve; but it will be understood that the invention is applicable to many of the wick carriers or holders which are adapted for the adjustment of the wick, it only being necessary to make a projection from the wick- 1 of a wick-holder arranged to move up and down with the wick, and a vertical rod arranged through a suitable bearing in the fount, so as to be guided in its vertical movement, the lower end of the rod constructed with a vertical spring-finger, the said finger constructed with a vertical slot and the wickholder with a corresponding projection adapted to engage the said springfinger, substantially as and for the purpose described.

2. Ina central-draft lamp, the combination of a vertically-guided wick-adjusting rod II, its lower end turned upward and forming a vertical spring-finger J, the finger constructed with a vertical slot K, and a wick-holding sleeve constructed with a vertical radial rib adapted to engage the slot of said spring finger, substantially as described.

3. In acentral-draft lamp, the combination of the sleeve D, arranged to slide vertically upon the central tube and to carry the wick, the sleeve constructed with a radially-proj ecting vertical rib F, constructed with a transverse opening G outside of the wick, and a metal band E through said opening G and outside the wick, the two ends of the band adapted to be engaged around the wick, with the vertically-guided rod II, constructed with a spring J at its lower end, having a' slot K therein, adapted to engage the said rib F, substantially as described.
